Supertech Engine Valves are engineered for high-performance street and racing applications, delivering exceptional strength, heat resistance, and precise fit.

Production begins with a one-piece forging, where the head is formed under a slow two-step process to maintain optimal material grain flow.

Each valve undergoes multiple CNC machining steps, stress-relieving heat treatments, and either nitride hardening or application-specific coatings.

Final grinding and our patented Superfinishing process

For use in turbocharged hi stress engines
